摘要：

A series of new poly(1,3,4-oxadiazole-amide)s have been synthesized by solution polycondensation of aromatic;diamines containing preformed 1,3,4-oxadiazole rings with phenoxyterephthalic diacid chloride or by the reaction of the same diacid chloride with p-aminobenzhydrazide resulting in a polyhydrazide-amide which was cyclodehydrated to the corresponding oxadiazolic structure. The new polymers were soluble or partially soluble in polar amidic solvents, were stable up to 375-400 degrees C in air and had a glass transition temperature in the range of 225-272 degrees C.
